Description Of Item: Polished hinged wooden box with two brass clips and a black interior 398 mm x 48 mm x 32 mm containing 17 hollow centred caps each containing one of the series of Munsell papers comprising the H 16 colour vision test. Reverse of each cap has a hand-written numeral from 1 to 16 relating to the correct placement by a subject with normal colour vision. The initial reference cap is attached to the box and has 'P' hand-written on the reverse. The ends of the box have a Dymo label H 16 affixed.

Historical Significance: The h 16 colour sorting test is a variant of the Farnsworth Panel D 15 test and L'Anthony Desaturated D 15 test. Its strong hues are claimed to fail only deuteranopes and protanopes. This set was manufactured by a group of employees of Coles and Garrard supervised by Judith Orenstein (Steward) in order to provide each of the company's branches with a Desaturated D 15 test. The boxes were made by Michael Sutton, husband of archivist Pamela Sutton. A few sets were available for purchase by non Coles and Garrard employees.
